Research Interests

My current research interests focus primarily on theoretical aspects of planetary sciences, especially in the context of exoplanetary astronomy. With my collaborators, I have been modeling planet formation and evolution around FGKM dwarfs to interpret the KEPLER results and make predictions. I am also investigating the theory of thermal tides to examine whether the model can explain the anomalously large size of hot Jupiters and how it is related to the weather in these toasted worlds. I have been working closely with radio astronomers to kinematically identify various substructures in protoplanetary disks with the ALMA data, such as gas rings, spiral inflow, pressure bumps, and disk eccentricity. Some of these features may be intimately related to planet formation. Furthermore, I am engaging in a calculation about the origin of nanodust in the present Solar System. Besides planetary sciences, I am also studying shock dynamics in the environments of star-forming clouds. My collaborators and I uncovered a fluid instability (i.e., drag instability) in turbulent molecular clouds.

I enjoy interacting with students (both undergraduate and graduate). If you are interested in my research, please feel free to contact me for research opportunities.
